The new Best Buy ad, discovered by Phone Arena, says the tablet will start selling “Tuesday.” Considering that next Tuesday is July 23 – and Google’s media event during which we believed the new Nexus 7 will be announced takes place on July 24 – it makes sense to assume that Best Buy would launch it a week later, on July 30.

The publication says that according to the tipster who sent the image, the Best Buy flyer is set to run next Sunday, or July 28.

While the July 30 date is implied rather than explicitly confirmed, the ad does clearly list the device’s price and some of its specs. We’re looking at a 16GB new Nexus 7 version that packs a 1920 x 1200 display, and costs $229.99, a price in line with previous leaks.

Furthermore, the tablet is listed as “Google Nexus 7″ and the device is apparently also shown in the ad, and marked as a “new” arrival. For what it’s worth, the device has a different wallpaper than the first-gen Nexus 7′s, similar to the current wallpaper of the Nexus 10.

That said, we’ll have to wait for Google to announce the tablet to get official details about its launch.
